The proposed computational framework opens up a new dimension in exploring the full potential of additive manufacturing. The current consideration of manufacturability is by no means comprehensive. Firstly, as can be observed in e.g. Fig. REF , the layers have varying thickness. By varying the material deposition rate and move speed of the print head [1]}, the layer thickness can be adjusted during fabrication, but only to some extent. An idea to reduce the variation is by imposing minimum and maximum length scales on each individual layer. Here the robust formulation [2]} may serve as a good starting point. Secondly, while the rotation of the build plate offers a possibility to greatly reduce or even eliminate support structures [3]}, it does not guarantee support-free fabrication for complex parts with complex curved layers. The geometric condition for support-free fabrication needs to be further investigated, and to be incorporated in fabrication sequence optimization. Thirdly, the rotation of the build plate potentially gives rise to interference between the print head and already deposited part. This issue is coupled with support-free process planning. A potential solution to this is to restrict the orientation of curved layers in the optimization.
